Ritual and nursing

The literature reveals that much of nursing comprises ritualized activity and behaviour and that these rituals have a significant impact on nursing practice. This study uses an ethnographic approach to uncover the meaning of ritual and its impact on nursing practice by examining the rituals embedded in Intravenous therapy management of four registered nurses working in two surgical wards in South Australia.

Managing intravenous medications in the non-hospital setting: an ethnographic investigation

Little published information exists about the issues involved in conducting complex intravenous medication therapy in patients’ homes. An ethnographic study of a local hospital-in-the-home program in the Australian Capital Territory explored this phenomenon to identify those factors that had an impact on the use of medicine in the home environment. This article focuses on one of the three themes identified in the study—Clinical Practice. Within this theme, topics related to the organization and management of intravenous medications, geography and diversity of patient caseload, and communication in the practice setting are discussed. These findings have important implications for policy development and establishment of a research agenda for hospital-in-the-home services.

N-acetylcysteine for antioxidant therapy : pharmacology and clinical utility

Glutathione is an endogenous antioxidant and has a ubiquitous role in many of the body’s defences. Treatment with N -acetylcysteine (NAC) has been shown to increase levels of glutathione. NAC has been proposed as a treatment for several illnesses. Objectives : The efficacy and tolerability of NAC was examined across a range of conditions to evaluate the evidence supporting the use of NAC for each indication. Methods : A literature search was conducted using PubMed. Information was also collected from other online sources including the websites of the Therapeutic Goods Administration of Australia and the FDA. Results : Reports ranged from case studies to clinical trials. There is strong evidence to support the use of NAC for the treatment of paracetamol overdose and emerging evidence suggesting it has utility in psychiatric disorders, particularly schizophrenia and bipolar disorder. NAC is safe and well tolerated when administered orally but has documented risks with intravenous administration.

Changes in intravenous fluid use patterns in Australia and New Zealand: evidence of research translating into practice

OBJECTIVES: To describe changes in the use of intravenous (IV) fluid by quantity and type in different regions of Australia and New Zealand. DESIGN, SETTING AND PARTICIPANTS: We conducted a retrospective ecological study examining regional and temporal trends in IV fluid consumption across Australia and New Zealand over the periods 2012-2013 and 2013- 2014, using national proprietary sales data as a surrogate for consumption, and demographic data from the public domain. RESULTS: More than 13.3 million litres of IV fluid were consumed in Australia and New Zealand in 2012-2013, and more than 13.9 million litres in 2013-2014, with colloid solutions accounting for < 2%. There was marked regional variation in consumption of fluids, by volumes and proportions used, when standardised to overall Australian and New Zealand values. There was no significant change in the overall volume of crystalloid solutions consumed but there was a significant decrease (9%; P = 0.02) in the ratio of unbalanced to balanced crystalloid solutions consumed. Consumption of all forms of colloid solutions decreased, with a 12% reduction overall (P = 0.02), primarily driven by a 67% reduction in the consumption of hydroxyethyl starch (HES) solutions. CONCLUSIONS: The amount and type of IV fluid use, as determined by fluid sales, is highly variable across Australia and New Zealand. However, overall use of balanced crystalloid solutions is increasing and the use of HES has decreased dramatically.
